HERMON L. VAN VALKENBURG, OF NORWOOD, OHIO, ASSIGNOR TO ALLIS-OHALMERS COM- PANY, A CORPORATION OF NEW JERSEY, AND THE BULLOCK ELECTRIC MANUFACTURING COMPANY, A CORPORATION OF OHIO.

ARRANGEMENT OF PROTECTIVE APPARATUS.

To all whom it ma concern:

Be it known t at I, HERMoN L. VAN VALKENBUno, citizen of the United States, residing at Norwood, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Arrangements of Protective Apparatus, of which the following is a full, clear, and exact specification.

My invention relates to protective apparatus for systems of high voltage and large amperage and to its arrangement relative to the bus-bars in power stations or sub-stations.

One of the ob'ects of my invention is to so arrange the ifferent poles of multipole switching apparatus and the bus-bars that long cables and complicated connections between the switches and bus-bars are avoided and so that the switches can be easily connected to or disconnected from the bus-bars.

A further object is to place the switches and bus-bars in a simple, compact and safearrangement so as to occupy a space as small as ossible and as is consistent with safety.

A still further object of my invention is to so construct, inclose and arrange the switches and bus bars that there is no danger of injury to the surrounding apparatus or to operator from arcs at the point or points of rupture, or danger of a shor/ circuit between the different bus-bars.

My invention consists in the details of construction and in the combinations and arrangements of parts described in the s ecification and set forth in the appended c aims.

For a better understanding of my invention reference is had to the accompanying drawings in which Fi ure 1 is a front elevation of the switc es, bus bars and their com artments, parts being removed for the sa e of clearness; Fig. 2 is a vertical section approximately along the line 2-2 of Fig. 4; Fig. 3 is a partial horizontal section along the line 33 of Fig. 2; and Fig. 4 is a partial horizontal section along the line 44 of'Fig. 2.

Referring now to the figures of the drawings, I have shown at 10 an inclosure having a rear wall 11, and divided into main sections A, B and C by vertical walls 12. Each section is divided into three main compart- Specification of Letters Patent.

switches 19, 20 and 21 which are Patented Sept. 22, 1908.

ments A, A and A, B, B and 13, etc., by horizontal walls 13 and each main com artment is again divided by horizontal wa s or partitions 14 into two sub-compartments, the upper one of which is a bus-bar compartment and the lower one of which is a switch compartment. All the walls are made from non-conducting, fire-proof material, the walls 1.], 12 and 13 being preferably made from cement or concrete and the horizontal walls or partitions 14 preferably consisting of slabs of slate or soapstone. There may be a greater number of vertical sections A, B etc. than are here shown, or there may be a less number, depending upon the number of auxiliary circuits connected to the bus-bars in the power station or substation. Also each vertical section may be divided into a greater number of compartments, depending upon the number. of busbars or the number of phases in the main distributing circuit.

At 15, 16 and 17 are shown three bus-bars of a three-phase circuit extending horizontall through openings 12 in the vertical wal s 12 and through the bus-bar compartments of all the sections A, B, etc., being secured to the rear-wall by insulating supports 18. multipole oil switch, the poles being separated forming three separate single-pole oil ocated respeotively in the three switch compartments,

Each section of the inclosure contains a each single-pole switch restin on one of the horizontal Walls 13. Thus t e contacts of each pole are located in a se arate oil tank which is isolated from the ot ers and se arated therefrom by fire-proof walls so t iat there can be no communication of an' arc" articular 1D from one pole to another. The

arrangement of the bus-bars and e single pole switches effects a great saving in wiring and ermits the switches of each phase to be with two terminal rods 23 and 24 located in msulating bushings. 25 extending outward through the cover of the switch. Located inan msulating bushing 26 carried by each horizontal partition 14 above each switch is a bar 27 having its upper end in the bus-bar compartment and its ower'endin the switch compartment. The upper end of the bar is provided with two laterally extending spring aws 28 formi one member of' a knifelade bus-bar disconnecting switch 29, the other member of which is a bar or blade 30 ivoted to a clip 31 secured to the bus-bar. he lower end of the bar 27 is provided with two forwardly extending spring jaws 32 adapted to engage the upper end of terminal rod 23 of the switch. In the rear wall 11 and extending into each compartment is an insulating bushing 33 in which is mounted the conductor 34 of the auxiliar circuit adapted to be connected to the busars. In this instance the end of the conductor 34 in the switch compartment is provided with two forwardly extending spring 'aws 35 which en the to of terminal ro 2,4. vThe s ring jaws 32 an are' ai'ranged'in line wit rthe ends of switch terminal rods 23 and 24 so that the switch can be connected to and disconnected from the end of conductor 34 and the bus-bar, by simply sliding the switch in and out of the compartment. Each tankis preferably provided with a handle to facilitate its insertion into the tank or its removal therefrom. r

I have rovided means whereby all the three sing e pole switches constituting the multiple switch for one auxiliary circuit can be simultaneously 0 rated from a point remote from the switdh. Located in front of the inclosure 10 and secured thereto by brackets 36 is a vertical rotary operating rod 37 for each grou of single ole switches com- .osir one of t c threease switches. I javc are shown switches of the rotary t pe each having a ve'rlicalspindle 38 ada ted to be rotated to open cl se the switch. At the top of each vertical spindle 38 isan arm or lever 39. Extending from the operating rod 37 opposite each switch compartment and in the same horizontal plane as the arm 39 on the spindle 38 is an arm 40. Connecting the arms 39 and 40 is a rod 41 consisting, in this case, of two short arms connected together by a edeeve so as to form a turn-buckle whereby thelength of the rod 41 ma be adjusted. The rod 41 and arm 40 on the operating rod are connected together in such a manner, preferably by a pin and nut 42, that the arm 40 and rod 41 can be easily disconnected when it is desired to remove the switch.

The switch and bus-bar compartments are ,adapted'to be closed by a fire-proof door 43 hinged in thiscase to the front of the inclosure. Preferably each door covers the front of one bus-bar compartment and the 56 corresponding switch compartment. Each bars and switches alternate each consisting of a plur door is provided with a slot 44 through which the operating rod 41 passes. In F1g. 1 the doors are removed from sections A and B for the sake of clearness. The doors are also omitted from Fig. 2.

It is seen that with the arrangement of switches and bus-bars here showna safeand compact structure is obtained, and the usual Letters Patent is:-
